IMPROVED WINDOW-SHADE FIXTURE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, L. A. TRIPP, of Middletown, in the county of Orange, and State of New York, have invented a new and improved Window-Shade Fixture; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the'same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a window-shade attached to its supports, part beingbrolten away to. show the con struction.

Figure Zis a detail cross-section of the same.

7 Similar letters of reference indicate corresponding parts. My invention has for its object to furnish an improved fixture for window-shades, by which the shade may be held at any desired elevation, and at the same time be free to be run up as may be desired; and it consists in the combination of the cap, sliding-bolt, and notched stationary ring with each other, as hereinafter more fully described.

A represents the window-casing. B is the roller, to which the shade C is secured in the ordinary manner.

I) is a plate, of such a size as to fit into the mouth of the cap E. The plate D has lugs orprojcctions, cl, cast upon it,-near its edge, to act as guides and stops to the sliding-bolt F. The cap E should be of such a size as nearly to coincide with the size of the roller B, and has slots through its rim, upon opposite sides, for the ds of the sliding-bolt F. The cap'E and plate D are secured to the end of the roller B by through them and into the end of the. said roller. If-desircd, the lugs d may be cast e D be dispensed witlnbut I prefer 'the construction first described. The ends of ast with lugs or projections upon'its sides at its centre, gh the cap E. G is a ring, cast solid with the bracket pin cast solid upon the cap E. The interior of the passage of .the en screws or nails passing upon the cap E, and the plat the bolt F are bevelled upon opposite sides, and it is c to act as stops to prevent it from dropping too far throu H, to which the end of the roller is pivoted by a pivotingring is smooth and circulan-ekcept at its lowest side, in which are formed two notches, the one shallow and circular, and the other deeper, and somewhat in the shape of a ratchctflooth, as shown inLfig. 2, so that, in drawing the shade down, the lower or projecting end of the bolt mayslide frcclyovcr the notches In allowing the shade to run up, if it is allowed to move slowly, the lower end of the sliding-bolt will drop into the deeper notch, and hold it securely in place; but if the shade is'allowed'to run up a little more rapidly, the bolt will assover the deeper notch without dropping into it,

extent, or to be stopped at any desired point.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the cap E, sliding-bolt F, and notched ring G, with each other, substantially as herein shown and described and for the purpose set forth.

The above specification of my invention signed by me this 28th day of May, 1867.
